GAS COGENERATION REFRIGERATING-SYSTEM, AND CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a show case 100 using a gas cogeneration refrigerating system 1 provided with an auxiliary refrigerating means 50 for displaying an article while refrigerating or cold-storing the article. SOLUTION: In this gas cogeneration refrigerating system 1 for constituting the show case 100 for displaying the article while refrigerating or cold-storing the article, a storage alloy side heat-exchanging part where a brine for a storage alloy of a hydrogen storage alloy refrigerator 10 utilizing exhaust heat of a micro gas-turbine 20 flows, and an auxiliary side heat-exchanging part where a refrigerant of the auxiliary refrigerator 50 flows are arranged inside a brine tank 30 stored with a main brine circulated through the show case 100, the main brine receives cold heat from at least one of the storage alloy side heat- exchanging part and the auxiliary side heat-exchanging part, and the refrigeration or the cold-storage is conducted in the show case 100 by the cold heat received therein.
